Re: [LinuxBIOS] romcc - Internal compiler error: Cannot find block dominated ....

[Doug Bell]

I had one version of code where it failed on a line
like:
if (speed==100) speed=0;

but problem disappeared if I did :
if (speed==100) speed2=0;

This may have been a factor in the first reporting of
the problem as well.
